Just a thought... May not be helpful... Could you use an array d1, d2 etc. to store the telephone numbers....that way you can easily pump out variable by variable using i2c 8 bits per variable ..

Hi Bernard, Hi Bernard, I don't want to mislead you. There are problems with mLoader as Jac as stated. I believe matrix are probably working on them? Still it would be nice to know the official matrix line? When I have had an issue with a warning message about bad response popping up, I have to remo...

Hi Graham, After looking at your schematic, I suspect that you are missing a 10k pull up resistor on the MCLR line... If this is floating then it can cause problems like you are experiencing . I would say that the pickit 3 when connected is pulling the MCLR line high and the pic is running... Discon...

Thanks Ben,

Martin's experience was very similar to mine with Mloader. Will load up the new version and come back to you....is there a specific version no to check against?

I have just received my EB006 v9 this evening and could not get it to work out of the box. I am running Windows 7 After some time I have managed to get the unit running and here's what I did: plugging the device to a USB port and watch the win USB driver load successfully I then went into device man...

Hi, There are a number of chips with CAN on board. Checkout the Microchip website selector .remember that you will need an external CAN chip to interface the Micro to the CAN network bus...check out the data sheet on the MM site...EB018 eblock.. You will see two chips on the board, one is the CAN ch...

Hi, This micro does not have any can features on board, however you can do it by using an e-block, click on the link and it will take you to the data sheet... http://www.matrixmultimedia.com/product.php?Prod=EB018&PHPSESSID= When build in your chart you just need to add the CAN module to your panel ...

Hi,
I have run 5 CAN modules at once, across two PC's on a LAN..

Can you post your code or me o have a look at?.

Hey Ben, I have just got off a project which involves engine control, management of the 2 MVA gen set, one MVA UPS, synchronous mains transfer switches and control plane. All of this was managed by Modbus protocol using embedded microcontrollers. From my research, it appears that Modbus is becoming ...

Hi Joe, If you can afford the professional version I would recommend you go with this. Even though you feel your a beginner, your learning curve will be rapid, and you will quickly push the boundaries of the student version with your Programme aspirations. If you are considering MIAC, I am building ...

Thanks Leigh, aaaahh...what you say makes sense, particularly with the high degree of variability across the range of cards. It was good to confirm that its operating as expected. The 700 msec init time is not going to be an issue I believe in most industrial applications as this call is generally m...

Thanks John for pointing me in the right direction on this one – mental note to self, should do a little more thorough search of the forum before put my hand up :oops: . I did actually read the tail end of that thread some time ago and did not look into it any further, there is quite a lot of good i...

Brilliant, many thanks John.

Will give it a try and come back to you....

All the best

Hi MM team, I am working with the GPS module attached to the MIAC system. The unit functions well as a GPS, and I am able to get all GPS data back to the display without any issue. I am testing out the SD card function on the GPS module using an example supplied with the MAIC system examples (FC 5) ...

Hi Donald,

is this what your looking for... i set all of the LEDs to off at the start of the loop, it now cycles around with all LEDs off to begin the sequence.

I hope i have understood your requirement

I agree with Enamul, 4k7 is very common. Here is another good article on how to clculate the pull up resisitor values http://www.edn.com/design/analog/4371297/Design-calculations-for-robust-I2C-communications . I t describes the imapct of capacitance and bus speed vs resistor values. It allso provid...

Just a further thought, I would a sixth relay on the load side of the transformer... In the event of a situation when the stabilizer can not maintain the regulation within the desired range, it disconnects the load to prevent damage to the equipment supplied by the stabilizer. This should be easy to...

Hi Uli, It was components with axial leads capacitors, discrete devices etc. As the epoxy dried it expands basically ripping the legs/leads from the components. Yes it was a large potting block of epoxy. the way we solved this was to place a thin layer of silicon grease around the component, then ap...

Hi Uli, A couple of points to keepin mind: What ever you use to waterproof should be kept thin as possible to allow heat transfer, Also the material you use should should have good heat transfer characteristics.. If it acts as an insulator then your temp readings will be inaccurate. Be careful with ...

Hi Ben, Jonny, I can also confirm that DPI causes all sorts of issues with display in all versions of FC V5, especially display of the MIAC image on the panel. I also the sawthe same config issue on beta dSPIC. I first noticed this back in V4 versions, and I think that Jonny fixed or was working on ...

Hi Graham,

I may have mis understood, can you use the potentiometer as a potential divider between the two rails. The wiper is connected to the input of the opamp configure as a 1:1 buffer amp.

Perhaps put a series resistor in between the wiper and iut of the op amp for protection..

Hi Graham, Check out this thread... Towards the bottom you will find a flow chart that drives a dual pot....I did this a little while ago, it's quite straight forward to get it going. It's also appeared to be repeatidly accurate. http://www.matrixmultimedia.com/mmforums/viewtopic.php?f=46&t=10869 Se...

Hi

Yes Steve, they work well... I have used the microchip versions on I2C interface. I think I may have posted something on this a while ago...

try searching on digital potentiometer

Hi,

I might be on the wrong track here, however, could you use a PWM output and a filter on the input of the op amp to generate your voltages?... It would be a much simpler cct and provides granularity of control via software.

Just a thought.
